Septic Drainer has an advanced formula that opens your septic system's failed soil that no longer drains. Drainage failures are caused by Hard Pan Soil. Septic Drainer is a safe all natural soil condititioner that creates voids in your Hard Pan Soil allowing liquid wastewater to drain again. Bio-Septic Boost eliminates a by-product of this Hard Pan Soil failure called Bio-Mat. Bio-Mat is a black slimmy organic material that found above a thin gray layer of hard soil that is known as Hard Pan Soil. Septic Drainer and Bio-Septic Boost are used by more septic professionals than any leading treatment to restore and maintain a septic system's wastewater drainage system.
